Dian Campbell and her neighbors in Fox Creek, Colorado, are scrambling to figure out how they'll get to Tuesday's caucus.

They've gotten so much snow, they can barely get out of her house, Campbell said.

"Oh, my gosh, we probably got another foot last night, and we already had another foot-and-a-half, so [we've got] 2 ½ to 3 feet," she said.

A shoulder-high snow drift is blocking her front door, and it's waist-deep at the back door, she said. They have dug out a little bit, but the snow has buried their carriage and almost covered a greenhouse and a shed.

Needless to say, the roads are impassable, but Campbell says she's determined to caucus for Mitt Romney.

"We've been on the phone together to see if we can put together a snow mobile patrol to pick people up because the roads in most of the county are impassable," she said.

The caucus is going to be in a house about two miles away, and Campbell had said they could use their horse if all else fails.

That's not going to work, either.

"We'd tried to get out our horse and cart to drive to the voting location, but as you can see, there is too much snow for the horse to walk, and the cart is completely buried," she said. "Looks like I will be walking there, pulling my daughter on a sled behind!"

Justin Jefferys had a different kind of struggle to get to the polls.

The 28-year-old has cerebral palsy, brain damage, is partially paralyzed on his right side and is legally blind.

He voted for the first time this morning in Lawrenceburg, Tennessee.

"Oh, yeah, it was exciting to me," Jefferys said with a laugh.

His mother, Jennifer Welker, said she didn't think he had the mental capacity to vote, but he often surprises her.

"He really makes his own mind up. It surprises me at times the things that he does understand, and the things he comprehends and the ideas he comes up with on his own," she said.

Welker said Jefferys watches CNN "every day, all day long" and often talks politics with his stepfather.

He originally planned to vote for Fred Thompson because he's also from Lawrenceburg.

"When Fred Thompson dropped out, he started listening to what Barack Obama had to say, and said 'that's who I want to vote for,' " Welker said. "He was adamant about it, and he's really thrilled that that's who he voted for."

Welker said their entire family voted for Obama.

"It's just a really good thing for him, and I'm really proud of him for doing that," she said.
